OIL-BURNING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 506,027, dated October3, 1 893. Application filed July 1,1892- Serial No. 438,667. (No model.)

To all whom it may concern:

Be it known that I, FRED L. BABcocK, a citizen of the United States,residing at Terra Cotta,McHenry county, Illinois, have invented certainnew and useful Improvementsin- Oil-Burning Apparatus, of which thefollowing is a specification.

The object of my invention has more particular reference to theburnersin which crude oil or petroleum is used to generate steam instationary boilers; and my invention consists in the features-anddetails of construction hereinafter described and claimed.

In the drawings, Figure 1 is a longitudinal vertical section takenthrough a steam boiler provided with my improved burner in line 1 ofFig. 2, looking in the direction of the arrow; and Fig. 2 is a verticalsection taken in line 2 of Fig. 1, lookingin the direction of the arrow.

In making my improved oil burning apparatus, I have preferred toillustrate and describe it in connection with astationary tubular steamboiler, A, which may be incased in brick work, or otherwise located andsupported as may be desired. I carry a pipe, B, from a tank or otherconvenient source of oil supply, and lead it into the fire box orcombustion chamber C.

In order to introduce the oil with sufficient force to deliver it in astream or jet, and also to supply a desired amount of steam for purposesof combustion, I lead a steam pipe D from the steam dome of the boileror other convenient place, and terminate the end of the steam pipe inthe oil pipe B, so that the oil and steam will be commingled anddelivered together into the combustion chamber. Theintroduction of thesteam causes the oil to be delivered into the combustion chamber in ajet or forcible stream, so that it will be carried fully in anddelivered at the desired place, without the use of pumps, or other tionsf. At the bottom of the combustion chamber, and leading forward from theperforated wall, I arrange a slab or plate F, made of tire clay or otherrefractory material, so as to be able to withstand the great heat towhich it is exposed in use. At the top of the perforated wall F, andleading forward into the combustion chamber, I arrange another slab orplate F made of similar material, and supported in place in anyconvenient way. I prefer, however, to arrange a longitudinal partition Gextending from the wall F forward as far as the slabs or plates F and FThis partition serves to supportthe weight of the slab F and is providedwith perforations through it, as is the wall F at the rearof thecombustion chamber. It divides the rear end of the combustion chamberinto two compartments, communicating with each other through theperforations in the partition G. Immediately behind the wall F isprovided a space H, and a number of perforations hlead into this spacethrough the wall F below the fire chamber.

, In operation the oil and steam are introduced into the combustionchamber through the pipe B, where they are lighted, and in which theycontinue to burn as long as oil and steam are supplied. Air passes upthrough the grate bars and supplies the requisite quantity of oxygen tomaintain combustion. The perforations, f, through the wall at the rearof the combustion chamber, are not large enough to permit all of theheat and products of combustion to pass through, but permit a desiredproportion to pass through into the space H. The rest of the heat andproducts of combustion are forced forward and around the upper slab orplate F when they are able to pass through the space, I, under theboiler. By thus forcing them forward they are brought into contact withthe lower side of the boiler near its end, so as to insure an equalheating of the boiler at that point,

as well as at others, and thus maintain an equable temperaturethroughout. As the'products of combustion pass back, the portionof heatand products of combustion that has passed through the perforations finto the space H join them, and are carried along with them to the endof the boiler, when they are all drawn back through the tubes of theboiler and pass out through the smoke stack J. As this is going on, airwill be drawn in through the openings h to mingle with the products ofcombustion that have passed through the perforated wall, and on up intothe channel or space I, so thatif the combustion has not been completedin the combustion chamber, it will be carried on as the heat andproducts of combustion are carried forward and through the boiler. Inthis way, and-by this arrangement and mode of operaation, I am able toefiect acomplete combustion of the oil and steam introduced, so as tosecure their greatest heat producing capacity for the generation ofsteam. Of course, it will be understood that I propose to apply my oilburning apparatus to any objects and uses to which it may be applicable,although, as above said, I have preferred to explain it in connectionwith a stationary steam generating boiler.

What I regard as new, and desire to secure by Letters Patent, is

1. In an oil burning apparatus, the combination of a combustion chamber,means for carrying oil and steam into the chamber, a perforated wall atthe rear of the chamber having a space arranged behind it, and means forintroducing air into the space from outside the combustion chamber, anda plate extending forward from the top of the perforated wall to force aportion of the products of combustion forward around its front edge,substantially as described.

2. In an oil burning apparatus, the combination of a combustion chamber,grate bars arranged in the bottom of the chamber, means for carrying oiland steam into the chamber, a perforated wall at the rear of thechamber, a plate extending forward from the perforated Wall and restingon the grate bars, and a plate extending forward from the top of theperforated wall to force a portion of the products of combustion forwardaroundits front 5 edge, sn bstantially as described.
